Exchange Rate Type per Company Code

Question

HI Experts,
In our system the conversion rates for EURX are maintained since there are several European companies working with the system.
Now we would like to use the same SAP-system for companies in China & Taiwan. In both countries there is an individual "official" exchange rate which does not equal the exchange rates stated from the German banks and thus fed into the system.
Is there any possibility to connect a company (code) with one particular exchange rate type? Since we are dealing with countries outside of the EU.
Thanks in Advance

Hi,
as you may have recognized, the assignment cannot be made on company code (or country) level, but only on currency level. In particular, this is table TCURF.
When (almost) all possible currency combinations (from-to) are redirected to rate type EURX, then this looks like standard SAP delivery settings that you can freely change according to your needs.
If you are not familiar with TCURF maintenance, however, you should be very careful here and test every change before importing it to the productive environment.
The basic idea that I have always followed for the same or similar requirements is that local rules for a particular rate type are always control the rates to be applied when converting from any foreign currency to the currency of the particular country.
If you are a China company and your local company code currency (curr.type 10) is CNY, then you have to make the following changes to table TCURF:
First, find out all the foreign (non-CNY) currencies that you are dealing with. This may include EUR, USD, and any other currency of the world.
Then, determine (or create) a new exchange rate type in table TCURV. This should be the rate type for your "own" rates. Let's name it rate type "L" (for Local rates). Note: you can use the standard M rate type as well, but it is more transparent if you define a separate one.
Then have a look into table TCURF and find the entries as follows:
Rate type: M
From-currency: all that you are using in your business (all non-CNY that you use)
To-Currency: CNY
Valid-from: find the recent entry for each combination
With all of these entries displayed, you will find that the alternate exchange rate type field (ABWCT) in these entries is set to EURX.
Now you want to create a new TCURF entry as follows:
Rate type: M
From: the same foreign currencies as above
To: CNY
Valid-from: a newer date than the last current entry
Alternate exchange rate type: L (your new rate type) - in case you want to use just M, then leave ABWCT empty.
If you are using the L type (which I recommend), then you have to add 2 new entries to TCURF for each foreign currency:
1.
Rate type:  L
From: foreign curr
To: CNY
Valid-from: 1.1.1800 (yes!)
Ratio from and to: as you want, it should be the same as in the corresponding M entry, usually 1:1, but it depends
Alternate exchange rate type: leave it blank.
2.
Rate type:  L
From: CNY
To: foreign curr.
Valid-from: 1.1.1800 (yes!)
Ratio from and to: as you want, it should be the same as in the corresponding M entry, usually 1:1, but it depends
Alternate exchange rate type: leave it blank.
Finally, in OB08, you have to maintain rates like
type L,  foreign curr to CNY
You are done
What is happening is the following (example you post a document in USD in your China company code)
Doc.currency USD --> must be converted to your local currency CNY
First, the system looks the current ratios for the M entry:
M, USD to CNY, valid from: recent, 1:1 and ABWCT = L !!!! (the entry you have added before)
Then it checks the ratios for L:
L, USD to CNY, valid from 1.1.1800, 1:1, ABWCT = blank
Based on TCURF, the system will look for the current rate entered under rate type L, your local rate )
Now what if a USD-based company has to post something in CNY? No changes there as the TCURF settings were not touched. They should look like this:
M  CNY to USD, alt.exch.rate type EURX (or blank)
If it is EURX, then the rates enterd under EURX rate type (once USd to EUR and then CNY toi EUR) are read and the cross-rate CNY to USD is calculated.
If it is blank, then the rate entered under rate type M is used.
In both cases, no change to your current process.
It works similar if the company code is EUR based.
The main idea is: redirect all M entries in TCURF where <anycurr> to CNY to the new rate type L, but leave all other TCURF entries untouched. Direction <any> to CNY are only relevant for the China company code, the rest of the world does not care about that conversion. They might be interested in conversions like CNY to <any>, like in the above example, CNY to USD, or CNY to EUR, but that could be their German or ECB rate, you do not have to care about.
